Definitions
- the invention relates to a vehicle lamp with at least one light function, with a housing with a light source in the housing and with one the housing final lens, being between light source and lens a light collecting lens arrangement is arranged between the light source and the light-collecting lens arrangement arranged a light-scattering lens arrangement is, the light collecting lens assembly is a Fresnel lens that is opposite to the optically-free cover plate (A) is arranged in a spatially recessed manner in the housing and the light-scattering lens arrangement surrounds the light source in a cap shape
- a vehicle lamp is known from German Offenlegungsschrift DE 196 47 357 A1 which has a housing which is covered by an end plate.
- a light source is arranged in the housing.
- a light-collecting lens arrangement is arranged, which is designed as a Fresnel lens.
- the Fresnel lens is included arranged spatially set back in the housing relative to the end plate.
- the End plate has light-scattering and / or in the known prior art light-gathering lens elements to combine with the Fresnel lens Predefined light distribution of the vehicle lamp and the one assigned to it Achieve light function.
- a disadvantage of this known vehicle lamp is that that the lens elements in the lens have a brilliant appearance the lamp is not given, since the lens elements in the free view from the outside prevent the lamp.
- a vehicle lamp with at least one light function with a housing, with a light source in the housing and with a cover plate that closes the housing is known, wherein a light-collecting lens arrangement is arranged between the light source and the lens, the light-collecting lens arrangement is a Fresnel lens, which is arranged spatially set back in the housing with respect to the firing disc, and the light-scattering lens arrangement surrounds the light source in a cap shape.
- the lens of the known vehicle lamp is referred to in JP 03 25 40 04 as "lens", from which it can be deduced that it exerts an optical effect and is therefore provided with optical elements. Such elements prevent a clear view of the lamp.
- the invention has for its object to provide a vehicle lamp, which has a brilliant appearance with a simple technical structure.
- the lens of the at least one light function is optics-free is trained because it allows a clear view of the lamp and a brilliant appearance is achieved.
- the light source is particularly advantageous to design the light source as a colored light source and / or the light-collecting lens arrangement and / or the light-scattering
- design lens arrangement as a color filter, because the advantage is achieved that the Luminaire can have any color design when switched off is independent of the signal function of the vehicle lamp.
- Figure 1 shows a horizontal section through a vehicle lamp, the one Has housing (G), which is covered by a cover plate (A).
- the Vehicle lights can have a single light function or one so-called multi-chamber luminaire, in which several light functions are integrated.
- a is not shown Socket arrangement of a light source (L) indicated only schematically in the housing (G) arranged.
- the light source (L) has a focal point (B) and can be white or emit colored light.
- the lens (A) is optically free and made of a clear or clear colored plastic.
- a light-collecting lens arrangement (SA) which is designed as a Fresnel lens, arranged.
- SA light-collecting lens arrangement
- this light-scattering lens arrangement (ST) cap-shaped and surrounds the light source, so that all essential In the housing (G) is spatially opposite the lens (A) sets back a light collecting lens assembly (SA) that acts as a Fresnel lens is arranged.
- SA light collecting lens assembly
- In the beam path between the Light source and the light-collecting lens arrangement (SA) is one light-scattering lens arrangement (ST) arranged.
- this light-scattering lens arrangement (ST) is cap-shaped trained and surrounds the light source, so that all essential light components get a pre-alignment by the light-scattering lens arrangement (ST), before they hit the light-collecting lens arrangement (SA).
- the light-collecting lens arrangement (SA) and the light-scattering lens arrangement (ST) are coordinated so that the vehicle lamp for the light function generates the required light distribution.
- the light-collecting lens arrangement (SA) extends in Form of a Fresnel lens set back in the housing (G) essentially above the entire area of the vehicle lamp.
- the light-collecting lens arrangement (SA) and / or the light-scattering Lens arrangement (ST) can be designed as a color filter.
- a clear lens (A) or a colored one transparent lens (A) and / or a clear or colored The light source thus results in any color design options Luminaire not switched on, the signal color of the light function can be complied with in accordance with the legal requirements.
- the generation of the light distribution by the light-scattering lens arrangement (ST) and the light collecting lens assembly (SA) is set back in the housing is generated and the lens (A) gives an insight into the lamp enables a brilliant appearance that reflects the depth of the lamp taught.
- FIG 2 is the light-scattering lens arrangement (ST), which is exemplary here is cap-shaped, shown in front view.
- This lens arrangement has, for example, a central optics area (ZO) with concentric arranged, light-scattering lens elements (LE).
- ZO central optics area
- LE light-scattering lens elements
- At the central Optics area (ZO) closes an area with also light-scattering Lens elements (LE), which are essentially in the direction of the Extend the center (M) of the central optics area (ZO).
- the light-scattering lens elements ((LE) can be used both with and with radii provided lens elements (LE) or as prisms.
- FIG 3 is a horizontal section through the light-scattering according to Figure 2 Lens arrangement (ST) shown. Examples are from the focus (B) of the light source (L), not shown, two light beams (LS) are drawn in illustrate the light-scattering effect of the lens elements (LE).
- Figure 1 is a comparable beam path for two light rays (LS) is drawn in also the light-collecting effect of the light-collecting lens arrangement (SA) clarified.

Description
wobei zwischen Lichtquelle und Abschlußscheibe eine lichtsammelnde Linsenanordnung angeordnet ist, die lichtsammelnde Linsenanordnung eine Fresnetlinse ist, die gegenüber der Abschtußscheibe räumlich zurückversetzt im Gehäuse angeordnet ist und die lichtstreuende Linsenanordnung, die Lichtquelle kappenförmig umgibt. Die Abschlußscheibeder bekannten Fahrzeugleuchte wird in JP 03 25 40 04 als "lens" bezeichnet, woraus abzuleiten ist, daß diese eine optische Wirkung aus übt und dem = zufolge mit optische Elemente versehen ist. Solche Elemente verhindern den freien Blick in die Leuchte hinein. Somit weist die bekannte Fahrzeugleuchte ein mangel = holes brillantes Erscheinungsbild auf.
